§ 37.3. Internal product temperature.
(a) The internal product temperature of frozen food shall be maintained at 0°F or lower except when the product is subjected to the conditions provided in § 37.2 (relating to air temperature). When the frozen food is subjected to such conditions the internal product temperature shall not exceed 10°F, except during further processing. In all cases the product shall be returned to 0°F as quickly as possible.
(b) When an accurate determination of internal product temperature of any case of frozen food fails without having sacrificed the packaged frozen food, representative packages or units shall be opened to allow inserting of the sensing element to the approximate center of the packages in question.
(c) Internal product temperature of cases of consumer packages of frozen food shall be determined in the following manner:
(1) Open the top of the case and remove two corner packages.
(2) Punch a hole in the case from the inside. The stem of the thermometer shall not be used for punching. The hole shall be positioned so that when the thermometer stem is inserted from the outside it fits snugly between packages.
(3) The temperature may be read after 5 minutes.
(d) Thermometers or other temperature measuring devices shall have an accuracy of plus or minus 2°F.
